微信小程序--点击事件参数传递

<van-row gutter="40" style="width: 100%;">
      <van-col span="8">
        <image  src="../../image/2048.png" background-size="cover" class="log" bindtap="playGame" data-item='game'></image >
        </van-col>
      <van-col span="8"> <image  src="../../image/红包.png" background-size="cover" class="log" bindtap="playGame" data-item='redPacket'></image ></van-col>
      <van-col span="8">3</van-col>
    </van-row>

使用 data-item传递参数
接收时使用val.target.dataset.item

  playGame: function (val) {
    wx.navigateTo({
      url: `../${val.target.dataset.item}/${val.target.dataset.item}`,
    })
  },
